Asteroid 7 Iris Orbit Diagram
This 3d orbit diagram is a feature of our 3D Solar System Simulator and shows the orbit of Asteroid 7 Iris with respect of the Sun and the orbits of the major planets. The position of Asteroid 7 Iris and the planets along their orbits in this diagram accurately represents the current configuration of the objects in the Solar System. This is an experimental feature and it requires a WebGL enabled browser. Please provide us feedback!

Distance of Asteroid 7 Iris from Earth
The following chart shows the distance of Asteroid 7 Iris from Earth as a function of time. Distance data is measured in Astronomical Units and sampled with a 2 days interval. The reported distances might be inaccurate around the times of closest approach for objects passing extremely close to Earth. The value of the distance of 7 Iris is also available as a real time updated value in the Live Position and Data Tracker.
Light Curve of Asteroid 7 Iris
The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 7 Iris, according to the most recent ephemerides data. Magnitude data is sampled with a 2 days interval and there might be inaccuracies for objects changing brightness very rapidly during the course of a few days. For comets there could be large discrepancies between the observed and predicted brightness because of their highly dynamic behaviour.
